Damian Lewis — who plays a shady hedge funder on Showtime’s hit series “Billions” — looked like he was trading inside information over dinner at Red Cat in Chelsea on Sunday night.

The British actor, a UTA client, was huddled at a corner table with a man who bore an uncanny resemblance to WME superagent Ari Emanuel. Some diners thought Lewis was being poached to switch agencies. But Emanuel is said to be in Brazil.

Sources say the other man was Broadway producer Tom Kirdahy, the husband of playwright Terrence McNally.
